Abstract- In this paper, contact force history in low velocity impact on laminated composite with simply-supported
boundary condition, using three different spring-mass models is investigated, analytically. Using two degree of freedom
spring-mass model, modified spring-mass model and static model, the dynamic force of impact is calculated and then
imposed on impacted place in the plate. To insure the accuracy of the present models, the contact force history
validated with experimental results available in literature. The results indicated that changing the mass of impactor
and velocity has significant effect on impact response and three models are in a good agreement with each other.
